Question

what is the potentiometer

Answer 1

A potentiometer is a manually adjustable variable resistor with 3 terminals. Two terminals are connected to both ends of a resistive element, and the third terminal connects to a sliding contact, called a wiper, moving over the resistive element. The position of the wiper determines the output voltage of the potentiometer. The potentiometer essentially functions as a variable voltage divider. The resistive element can be seen as two resistors in series(potentiometer resistance), where the wiper position determines the resistance ratio of the first resistor to the second resistor.

A potentiometer is also commonly known as a potmeter or pot. The most common form of potmeter is the single turn rotary potmeter. This type of pot is often used in audio volume control (logarithmic taper) as well as many other applications. Different materials are used to construct potentiometers, including carbon composition, cermet, wirewound, conductive plastic or metal film.

Answer 2

Hey !!

1. It is a three terminal resistor where the resistance is manually varied to control the flow of  electric current.
2. It consists of three terminals among which, two are fixed and one is variable.
3. In this, two fixed terminals are connected to both ends of resistive elements known as track while the third terminal is connected to sliding wiper.
4. In potentiometer, the wiper which moves along the resistive element varies the resistance of the potentiometer.
5. The resistance of the potentiometer gets changed when the wiper is moved over the resistive path.

GOOD LUCK !!
